What tools do you need to OpenShift?

● There are an endless options of tools available● Your tools of choice varies with your

○ Preferences○ Tasks○ Roles○ Operating systems○ “View” of the world

● Do you have the permissions to install your tools of choice?○ Do you have full control over your system or is it manage by an enterprise?

■ Some organizations are very opinionated and locked down■ Others companies may allow some, or controlled/approved installations■ While still other will give out full permissions to specific roles/users

oc: a CLI for OpenShiftThe oc command line tool is used to interact with the OpenShift and Kubernetes HTTP API(s). oc is an alias for openshift cli and commands are verb focused.

There are 5 base verbs and 6 command groups can be used to manage both Kubernetes and OpenShift resources. Most common verbs and subcommands are documented in the CLI help.

oc is a first class tool that can help you interact with openshift regardless of your role!

> oc project <projectName> --display-name="<display_name>"Now using project "rhsummit19" on server "https://192.168.42.101:8443".

> oc new-app --template=django-psql-persistentRun 'oc status' to view your app.

> oc logs -f bc/django-psql-persistentPush successful

> oc describe bc django-psql-persistentName: django-psql-persistent(additional output omitted)

> oc expose service django-psql-persistentroute.route.openshift.io/django-psql-persistent exposed

> oc start-build django-psql-persistentbuild.build.openshift.io/django-psql-persistent-2 started

> oc statusView details with 'oc describe <resource>/<name>' or list everything with 'oc get all'

odo: a CLI for Developers

odo is a new CLI for OpenShift that is tailored for developer syntax and workflows.

Goal is to make it simple for a developer to create an app, add components (like a database) and expose it without needing to know Kubernetes.

odo is a affectionately called “OpenShift DO!”

> odo create wildfly backendComponent ‘backend’ was created.To push source code to the component run ‘odo push’

> odo pushPushing changes to component: backend

> odo storage create backend-store --path /data --size 100MAdded storage backend-store to backend

> odo create php frontendComponent ‘frontend’ was created.To push source code to the component run ‘odo push’
